<optimized out>

[Der Herr Hofrat]

HI !

how can I prevent GCC from optimizing away a specific variable ?
lets say I have something trivial like

 int i;
 i=3;
 printf("%d\n",i);

then gcc with -O2 seems to directly push 3 on the stack and call printf
and never used a local variable so I can't access it in the debuger. Is
there any simply way of preventing this other than doing stupid things like
introducing some useless statements to force a local variable but without
turning of -O2 for the entire file ???
